OK, let's work through this together. We're starting with 906 and we're going to multiply it by 41, which means we add 906 to itself 41 times.
Step 1: 0 + 906 = 906
Step 2: 906 + 906 = 1812
Step 3: 1812 + 906 = 2718
Step 4: 2718 + 906 = 3624
Step 5: 3624 + 906 = 4530
Step 6: 4530 + 906 = 5436
Step 7: 5436 + 906 = 6342
Step 8: 6342 + 906 = 7248
Step 9: 7248 + 906 = 8154
Step 10: 8154 + 906 = 9060
Step 11: 9060 + 906 = 9966
Step 12: 9966 + 906 = 10872
Step 13: 10872 + 906 = 11778
Step 14: 11778 + 906 = 12684
Step 15: 12684 + 906 = 13590
Step 16: 13590 + 906 = 14496
Step 17: 14496 + 906 = 15402
Step 18: 15402 + 906 = 16308
Step 19: 16308 + 906 = 17214
Step 20: 17214 + 906 = 18120
Step 21: 18120 + 906 = 19026
Step 22: 19026 + 906 = 19932
Step 23: 19932 + 906 = 20838
Step 24: 20838 + 906 = 21744
Step 25: 21744 + 906 = 22650
Step 26: 22650 + 906 = 23556
Step 27: 23556 + 906 = 24462
Step 28: 24462 + 906 = 25368
Step 29: 25368 + 906 = 26274
Step 30: 26274 + 906 = 27180
Step 31: 27180 + 906 = 28086
Step 32: 28086 + 906 = 28992
Step 33: 28992 + 906 = 29898
Step 34: 29898 + 906 = 30804
Step 35: 30804 + 906 = 31710
Step 36: 31710 + 906 = 32616
Step 37: 32616 + 906 = 33522
Step 38: 33522 + 906 = 34428
Step 39: 34428 + 906 = 35334
Step 40: 35334 + 906 = 36240
Step 41: 36240 + 906 = 37146

So, 906*41 = 37146
